Learning about QR Codes

QR code 

QR stands for Quick Resource. Denso Wave, a subsidiary of Toyota Motor Corporation, originally developed the concept of QR codes which were designed as a way to track parts by vehicle manufacturers. For example, common data stored in QR Codes are web addresses, actions to download a MP3 file, dial a telephone number, or even invoke an email with a predefined sender’s address. Today, QR Codes are use in magazines, business cards, signs, and clothing amongst other places even on the World Wide Web.

The data capacity of a code ranges based on the type format it encodes.

Numerical only

Max 7,089 characters

Alphanumeric

Max 4,296 characters

Binary (8 bits)

Max 1,817 characters

Compared to barcodes, QR codes can hold up to 7,089 characters opposed to the 20 digits limit possessed by barcodes.  In the Intel(R) Development Environment Beta, QR Codes make it very convenient to navigate to workspace on your mobile device(s) especially since the associated URLs are very long.

Accessing the Preview On Device(QR Code) menu option in the Intel(R) Development Environment Beta
The Preview on Device operation displays a dialog with a QR Code with the URL to the selected HTML file. For mobile device viewing, a QR Code scanner app is required to decrypt the QR Code to navigate to the URL on your device’s browser. Use Tools > Preview on Device to view the QR Code for the selected HTML file.
